MOVEMENTS OF THE ALIMENTARY CANAL. 695 large curvature by an abrupt change of direction. The pyloric partmakes an angle, therefore, with the body of the stomach and differsfrom the latter in its musculature, the macroscopical and microscopi-cal characteristics of its mucous membrane, and in its functionalimportance. The main body of the stomach falls into two sub-divisions, whose line of demarcation is, however, indefinite. Thefundus proper is the blind, rounded end of the stomach to the leftof the cardia and projecting toward the spleen. The intermediateor prepyloric region shows in many animals a characteristic struc- Pyloric Jaartofstemaior antrum hylon Position oftransverse oand. Fundus orprepyloric region.

It is in this region that the hydro-chloric acid of the gastric juice is mainly secreted. The Musculature of the Stomach.—The musculature of thestomach is usually divided into three layers,—a longitudinal, anoblique, and a circular coat. The longitudinal coat is continuousat the cardia with the longitudinal fibers of the esophagus; it spreadsout from this point along the length of the stomach, forming a layerof varying thickness; along the curvatures the layer is strongerthan on the front and posterior surfaces, while at the pyloric end itincreases considerably in thickness, and passes over the pylorus tobe continued directly into the longitudinal coat of the layer of oblique fibers is quite incomplete; it seems to becontinuous with the circul
